Amoxicillin is a broad-spectrum antibiotic prescribed by veterinarians to treat various infections in dogs and cats. It inhibits the growth of bacteria by preventing the cell wall formation of the bacterial cells. Amoxicillin should only be used to treat bacterial infections and not viral or parasitic infections. It has also been known to treat wounds, skin infections, tooth abscesses, infections of the lower respiratory tract and many others. Plus, it comes in a capsule form, so you can disguise it in a pill pocket. Customers may receive this drug under the names Amoxi-Tabs, Amoxi-Drops, Robamox.

What is Amoxicillin?

Amoxicillin is a broad-spectrum antibiotic. Antibiotics are drugs which kill or stop the growth of bacteria. Amoxicillin is very safe and often prescribed for infections while waiting for laboratory results.

What are the benefits of Amoxicillin?

Amoxicillin is very useful for the treatment and prevention of a wide variety of bacterial infections. Treats ear infections, urinary infections and skin infections (infected bite wounds). Also effective against upper respiratory, bladder and dental infections.

How is this medication given?

Give this medication exactly as directed by your veterinarian. Amoxicillin can be given with or without food. Give all of the amoxicillin even if your pet appears to be better. Symptoms may improve before the infection is completely treated.

How does this medication work?

Amoxicillin blocks the bacteria from making a cell wall (the outer protective covering of the bacteria). As a result, the bacteria usually die.

What results can I expect?

Amoxicillin is absorbed well from the digestive system and is distributed to many body tissues, making it effective against infections in multiple organs. It is active against many different types of bacteria. It is usually given two to three times a day for a number of days. If doses are missed or the entire treatment regimen is not completed, the infection could recur or worsen. Consult your veterinarian if the animal's condition does not improve or worsens after beginning treatment with Amoxicillin.

    What an antibiotic!

    By Hewhomustbeobeyed on Feb 28, 2020

    The primary determinant in reviewing a prescription drug is if it works. And the amoxicillin 250 mg caps certainly did their job--quite as expected. So did Chewy--quite as expected . . .
